After years of careful preparation and months of campaigning, Emmanuel Macron and his allies are about to take control of the euro area’s second-biggest economy. Typically associates from the elite French schools where the new president studied, or his time in government under outgoing President Francois Hollande, Team Macron were first dismissed as fantasists and then faced attacks from all sides. Now they are going to be taking decisions that will affect hundreds of billions of dollars in global trade from energy to finance and defense. Here’s a run-down of his closest aides and the potential candidates for joining his government.

High-Flying Contemporaries

Alexis Kohler, 44
The salt-and-pepper-haired adviser may have as many diplomas as his boss. He’s tipped to be Macron’s chief-of-staff after previously holding the same post when the candidate ran the economy ministry. Kohler is currently chief financial officer of MSC Cruises in Geneva.Studied at Sciences Po, the Sorbonne law school, ESSEC business school and ENA.

Ismael Emelien, 30
Glued to his cellphone, hidden behind large glasses, the low-key campaign strategist is steering Macron through the dangerous waters of French politics. He started out in politics on Dominique Strauss-Kahn’s 2006 team and then worked for global communications firm Havas Group before joining Macron at the economy ministry.Studied at Sciences Po.

Julien Denormandie, 36
An engineer who worked on Iran for the French Treasury and then at the embassy in Cairo advised Macron on trade during his time in government. Now an aide on the campaign team and mentioned as a possible specialist adviser on that topic if his boss wins.Studied at France’s top schools for land management and engineering, before getting an MBA at Paris Engineers School.

The Veterans

Richard Ferrand, 54
A Socialist lawmaker who’s been in politics for two decades and the national parliament since 2012, Ferrand was one of Macron’s earliest backers. He defended the young minister’s economy bill in parliament and helped him start his political movement in April last year. Could get a major cabinet position.Studied law in Toulouse.

Jean Pisani-Ferry, 65
Former head of Hollande’s long-term policy unit, Pisani-Ferry has also worked for the European Commission and the International Monetary Fund and was president of the Bruegel research institute between 2005 and 2013.Graduated from a French technology institute.

Gerard Collomb, 69
Socialist senator and mayor of Lyon was another early supporter of Macron, delivering France’s No. 3 city to the candidate with 30 percent of the vote in the first round of the election. He is the oldest of Macron’s inner circle and one of many possible candidates for prime minister.Former teacher, studied Greek and Latin literature.

Macron said before the vote that he’s decided who he wants as his prime minister, though he refused to say who it was. He hasn’t given much indication of who else might be in his cabinet, but says he wants people from outside the usual political circles. With no established party to draw on, Macron is likely to seek allies from both sides of the political spectrum.
